What did you use to bend your injection lines?

What tool worked the best? I'll be setting a set up on my truck soon and looking for the easiest way to do it.

If I ever decide to bend lines again, I'll shoot myself first.

I've watched my buddies bend big lines on pulling tractors. It's tough to impossible to make them look really good.

thanks for the link Jeff, I searched and couldn't find much.

Brake line bender

I have a rolling tubing bender that I got from Eastwood. Works like a champ on injection lines. Makes tight clean bends. I think I paid around $50 for it.

Pretty easy to make them look good

I'll second the brake line bender. Works excellent.

I know a certain member of this board bends them with his bare hands. And they look good.
He's kinda a real life Chuck Norris though..

Bare hands and a 3/4in box end wrench makes quick work of them.

You might consider using some 1/4" soft copper tubing to make prototype lines, adjusting as needed for the best fit. Then bend the fuel lines to match.

I used one of the typical Shoe & Die type tube benders found at the local HVAC supply shop.

In the case of my VE fueled engine, I found it most attractive to start at the injectors . . . ..

. . . having the slack end-up at the injection-pump.

I don't know where you might put the slack dealing with another IP.

Good luck.

Pardon my dumb question, and the more I think about it the it makes sense. But do injection lines all have to be the same length?

Yes.

So, Chuck Norris isn't real?
Whew! Here I was thinking Superman was a fictional character! :hehe:

I did mine using brake line as prototypes, and a good Snapon line bender
Starting with number six cylinder as it has the farthest to go
worked backwards from there
Lines came out beautiful
One thing I did find out the hard way - you must make absolutely certain that the lines are perfectly perpendicular to the pump and the injectors or the line will absolutely leak when you try to tighten the lines up - once I had that figured out - there were no issues

Yes.

Why?


The fuel is a solid, once the air is out of the lines, the amount pumped through the length of line is the same, doesn't matter if the line is 1 foot long, or 10 feet long...once the air is out, it should be the same volume pumped through it.

....or I'm I missing something?:what:

Fuel isn't solid, at injection pressure it's quite compressible. Think about it, if it wasn't how would common rail ever work? On a mechanical it comes down to timing and rate.

Well then....the lines have to be the same length.:lolly:

Thanks for the clarification.

It took me a while to comprehend this length theory, until I found out that a liquid IS IN FACT COMPRESSIBLE.
It seems that the fallacy that liquid is supposedly NOT compressible is more prevalent than it should be.

Here's a chart that indicates that liquids are in fact compressible:

I Also used copper line first. Then used it as a pattern on the line.
Used a cheap Bender.
Turned out decent
